摘要

太阳图像的质心坐标需要在基于APS的数字太阳传感器中计算。通常的“质心”算法浪费时间，特别是当太阳图像的面积远远小于APS的时候。提出了一种新的快速计算太阳图像质心的方法。新算法的优点是提高了计算速度，保证了精度的要求

A fast algorithm of attitude measurement for APS-based digital sun sensors

The centroid coordinates of the sun image on the APS is required to be worked out in APS-based digital sun sensors. The usual `centroid' algorithm wastes time, especially when the area of the sun image is far smaller than the APS's. A new and faster method is offered to calculate the centroid of the sun image. The merit of the new algorithm is that it can improve the speed of the calculation and ensure the demand of precision
